style: [patch 1/22] use /r/3648/ to reorganize includes

dev: Include basic devices in NULL ISA build

This patch enbles use of the basic PIO devices as part of the NULL
build. Although it might seem counter intuitive to have a PIO device
without being able to execute a driver, this change enables us to
break a device class hierarchy into an ISA-agnostic part, and an
ISA-specific part, without requiring multiple-inheritance. The
ISA-agnostic base class is a PIO device, but does not make use of the
port.

dev: make BasicPioDevice take size in constructor

Instead of relying on derived classes explicitly assigning
to the BasicPioDevice pioSize field, require them to pass
a size value in to the constructor.

SE/FS: Put platform pointers in fewer objects.

Not all objects need a platform pointer, and having one creates a dependence
on their being a platform object. This change removes the platform pointer to
from the base device object and moves it into subclasses that actually need
it.

Includes: Don't include isa_traits.hh and use the TheISA namespace unless really needed.

arch: nuke arch/isa_specific.hh and move stuff to generated config/the_isa.hh

Major changes to how SimObjects are created and initialized. Almost all
creation and initialization now happens in python. Parameter objects
are generated and initialized by python. The .ini file is now solely for
debugging purposes and is not used in construction of the objects in any
way.

make our code a little more standards compliant
pretty close to compiling w/ suns compiler

add dummy return after panic()/fatal()
split out flags by compiler vendor
include cstring and cmath where appropriate
use std namespace for string ops

little fixes i noticed while searching for reason for address range issues (but these weren't the cause of the problem).

RangeSize as a function takes a start address, and a SIZE, and will make the range (start, start+size-1) for you.

Updated Authors from bk prs info

New directory structure:
- simulator source now in 'src' subdirectory
- imported files from 'ext' repository
- support building in arbitrary places, including
outside of the source tree. See comment at top
of SConstruct file for more details.
Regression tests are temporarily disabled; that
syetem needs more extensive revisions.
